Chapter 30
Trust in Science

“……”

Bringing Lu Chen and the others back to the Demon Slayer Corps base, Kocho Kanae was in a state of bewildered daze.

On the one hand, she was grieving for her lost teammates, and on the other hand, she was still immersed in the shock of the Richelieu's simultaneous cannon barrage.

She couldn't understand what kind of power it was, and even when Lu Chen explained it to her, she couldn't understand.

“Sister!!”

A girl with black-purple hair and the same butterfly hair ornament as her sister rushed over to Kanae.

Kocho Shinobu.

At this time, she was still a straightforward and slightly competitive little girl.

“Where are the other companions?”

“We encountered Upper Rank Two, Douma, they are all…”

Kanae's voice dropped.

“I see…”

Shinobu understood.

The Demon Slayer Corps had a very high casualty rate; death was a common occurrence.

From the moment they picked up their Nichirin blades, they had already accepted this reality.

“Wait, you encountered Upper Rank Two? But you came back alive?! Meaning…?”

Another member widened his eyes, looking at the few people behind Kanae.

“Who are these people…?”

“Hello.”

Lu Chen greeted the members of the Demon Slayer Corps.

“We are from another world, here to physically transcend the Twelve Kizuki and Muzan Kibutsuji.”

……

About half an hour later.

The upper echelon of the Demon Slayer Corps were all present.

They received Lu Chen and the Kanmusu as honored guests.

The reason was simple: according to the Demon Slayer Corps' usual assessment standards, killing 50 ordinary demons, or defeating a member of the Twelve Kizuki, could make one a "Hashira," the highest-ranking cadre.

Lu Chen and his companions had one-shotted Upper Rank Two, they were practically gods descended to earth.

Although some members were initially wary of strangers, after listening to Kocho Kanae's account, and with her assurance, their doubts were quickly dispelled.

They had saved Kanae from Douma's subordinates, and both sides had a common enemy, "demons."

So in a way, they were teammates.

Both sides sat on tatami mats, and the Demon Slayer Corps' logistics personnel brought out fruits and snacks, allowing the people from the two worlds to interact with each other.

“Sister, how did you eliminate Douma?”

Shinobu huddled next to Richelieu, curiously asking.

“What weapon did you use? Why didn't I see your sword?”

“Four-barreled 380mm gun Mle1935, along with 16-inch capped armor-piercing rounds and high-explosive rounds.”

Richelieu gave her an answer she couldn’t comprehend.

“???”

Shinobu looked at Kanae with a bewildered face.

Kanae said she didn't understand either, so don't ask her.

“What breathing technique are you training in?”

Another Demon Slayer Corps member with golden hair asked.

From his intuition, he felt that these people's physical strength was incredibly strong, even far exceeding his own, who trained in the Flame Breathing technique.

“We rely on magic cube power and reactor energy, reactor, you understand? Hydrogen element fusion that kind of thing?”

Beifa patiently tried to explain to him what fusion and fission were.

“???”

Rengoku Kyojuro was completely baffled.

The concept of a reactor was a bit too advanced for the natives of the steam age, he couldn't even understand the principle.

“……”

“Let's discuss the matter of slaying demons.”

Seeing that the communication between the two sides was completely a case of talking past each other, Lu Chen took over the conversation.

“As you can see, one of our goals is also to kill Muzan Kibutsuji and the Twelve Kizuki. I believe our goals are the same in this regard.”

“Indeed.”

A young man with a near-disfigured face and a somewhat frail body walked out of the inner room.

Ubuyashiki Kagaya, the head of the Demon Slayer Corps.

“Killing Muzan is also the purpose of the Demon Slayer Corps' establishment.”

“The Ubuyashiki family has hunted him for nearly 1000 years, but none have succeeded.”

His tone was calm, his speech polite, but due to his poor health, he appeared somewhat weak.

“Is there anything we can help you with?”

“Do you know where the remaining Kizuki and Muzan Kibutsuji are?”

Kotetsu eagerly asked.

“I don’t know.”

Ubuyashiki Kagaya shook his head.

“Demons are inherently elusive, the Upper Ranks and Muzan are even more mysterious, rarely appearing in public.”

“Even when they do appear occasionally, they often catch the Demon Slayer Corps off guard, causing us heavy losses.”

“……”

Just as Lu Chen expected.

The trouble with this mission wasn't whether they could defeat the demons.

It was how to find Muzan and the other Kizuki.

The island nation wasn't that big, but if Muzan was determined to hide, finding him wouldn't be easy.

“Speaking of which, we may have encountered many Upper Ranks, but unfortunately, our members didn’t have the opportunity to report to us.”

“By the time the support forces arrived, they were usually already killed by demons.”

Kagaya sighed.

Similar to what Kanae had encountered.

After encountering powerful demons, in many cases, the Demon Slayer Corps members were directly killed and silenced, and their teammates couldn’t support them in time.

“So we need to lure them out… ”

Lu Chen thought for a moment.

“So many demons scattered throughout the country, catching them one by one would be a hassle… if only we could gather them all together…”

“Perhaps we need to figure out a way to lure Muzan and the remaining Twelve Kizuki out to fight us?”

“Ah?!”

The rest of the Demon Slayer Corps were simply shocked.

Normally, encountering one Kizuki was enough to give them a hard time, this person actually wanted to gather all the demons together?!

“Cough cough——”

“Mr. Lu, Muzan Kibutsuji is extremely powerful, even the late Yoriichi Tsugikuni could not completely eliminate him, don't underestimate him.”

“Aside from Sun Breathing and the sun, there may be nothing in this world that can kill him.”

Ubuyashiki Kagaya kindly reminded him.

“……”

“Only the sun can kill Muzan? That theory is novel, but we can also do it.”

Lu Chen smiled.

“What is the essence of the sun? A large fireball constantly undergoing hydrogen and helium fusion, sunlight is just light containing ultraviolet rays and heat radiation.”

“Even if Muzan is truly incredibly tenacious, and only sunlight can kill him, we can use technical means to create a mini sun to send him and the other demons to heaven.”

“!!!”

The others immediately held their breath.

Demons fear the sun, and this man actually said he could create an artificial sun!

What kind of power was this?!

With such technology, what were the Twelve Kizuki and Muzan Kibutsuji but mere chickens and dogs?!

“There is such a divine weapon?!”

“What is it called?!”

Kagaya's pupils constricted, and he hurriedly asked.

“Hydrogen bomb.”

“Ah?”
